IMPROVEMENT IN N'EEDLE-HOLDER VI'CILR.

SEWING-MACHINES.

The Schedule referred to in these Letters atent and making parl: of the same.

To all whom it mar/concern Beit known that we, CHARLES PARHAM and Gnonen A. SMITH, of the city of Philadelphia, and State of' Pennsylvania, have invented a new and useful Improvement in Sewing-Machines, consisting nf an adjustable needle-clamp and-holder; and we do hereby declare the following to be a full and exact description of the same,

reference being had to the annexed drawings, making a part of this specification, in which- L Figure 1 is a View of a straight round needle-bar or shaft with the adjustable clamp for needle.

4Figure 2, a longitudinal sectional viewl of the saine.

Figure 3, a detached view of the clamping-device complete.A

Figure 4, a similar view of the needle-holder or piston. A 4

Our invention-has for its object the-exact adjustment of the needle in all its relations to the other parts of the machine; and

It consists of a transverse hole in the end of the needle-bar,shaft, or lever for theinsertion Vof a needleholder or piston, the said bar,.shaft, or lever heilig slotted upwards. A ring or band' with a set-screw surrounds the whole forthe purpose of .firmly clamp-l ing the parts together.

To enable those skilled in the art to make and use our new clamp, we will describe it more fully.

Fig. 3 is the clamp and needle-holder complete, in which B is the clamping-band, having a suitable hole .through its sides for the. reception of the needleholder G.

The baud B. has a set-screw,V e, to secure the whole device to the needlebar or shaft A.

C is the needle-holder, of needle.

'd is the set-screw to secure the needle.

bis an eyelet or hole'for the guidance of the thread to,needle f.

In gs. l and 2 a represents the slot of needle-shaft or bar for clamping the several devices together; also, for reception of upper end of needle, In lig. 2, 'at C, is shown the larger hole for reception of needle-holder or piston;

In attachinglthe needle-holder to the end of a level' of a sewingmachine, or to the bar or shaft, a holeV 0f the saine gauge as .needle-holder .0, g. 2, is drilled, transversely through end of bar or shaft or lever. The shaft or lever is slotted upwards of the same, or about the same, gauge as-shank of needle. ring or band-clamp B is placed upon bar or shaft, as represented in figs l vand 2. The'holes in 4sides of with a hole for the insertion clamp beingvadjusted to correspond with .hole in bar or shaft, then the needle-holder or piston is in erted, as represented in figs. 1, 2, and 3. The needle-being made fast by screw d, the whole is now rmly clamped together by screw e. 4 i

lTo adjust or to take out the needle, the loosening of its screwis only requisite, as in the ordinary mode. Having the needleadj usted perpendicularly, to Aadjust it'laterally nnloosen the screw e of clamp B, then move the needle-holder as desired, then tighten clamp'. vHaving thc-Whole securely attached, pass the thread down through eyelet at `b to needle jl It will be observed thatif the clamp or band is loosed inthe said combination, that each piece of the clamping-device performs other offices, namely, the needleholder in its position prevents the band or ring from becoming detached from the shaft or -bar,and by the insertion of the shank of 'the needle in needle-holder or piston, the said holder or piston-will not .fall out, andthe end of needle .passing upwards through holder or piston between slot, the sides of slot prevent the needle-holder or, needle from s winging or turning around out of a perpendicular line. 'p

We also desire it to be understood that we do not confine its application to a straight needle-shaft or bar, as used in the Singer, Howe, or Parham sewing-ina- -chine,b.ut also to such sewing-machines that use a curved needle, 'as the Vheeler and Wilson; and that lwe do not confine ourselves to a ring-clamp for around needle-shaft or bar; but it may be modified so as to confornlto any-shaped needle-bar, shaft, or lever.

Having now fully described'four invention What we claim as new, and desire to secure by Let- AtersE'atent, is-

l. The combination of the clamp or-band B and needle-holder C, constructed, arranged, and operating as and for the purposes set forth.

2. The combination of clamp or band B, needle- Then theV holder C and needle-bar or shaft A, constructed and arranged as and for the purposes set forth.

3. The combination of the needle-bar, having a slot, (aand hole C, withthe needle-holder and clamp B, constructedand arranged for the purposes set forth. 4. The combination of the eyelet l), needle-holder O,

Aand clamp B, arranged ,as and for the purposesl set forth.
